Chapter 2 Preparing for Installation
1 - IEEE class 3 device | 17.3 | W |
|
|
|
total output power | 284 | W |
|
|
|
Total heat dissipated by system = (284/.75) * 3.415 = 1293 BTUs/hr
Note Although a class 3 device needs 15.4 W to power up, 17.3 W need to be generated from the backplane in order to have 15.4 W at the switch port. 17.3 W comes from the
